After migrating the ethernet interfaces from the good old Perl days the smp-affinity node yet has no effect anymore as the code is still missing (my bad, sorry).
I wonder if it is still relevant in current NOS devices as CPUs can be added dynamically on virtualized devices.
I suggest to drop the `smp-affinity` node and rather use `tuned` instead with the network-throughput or `network-latency` profile
* network-throughput: Profile for throughput network tuning. It is based on the throughput-performance profile. It additionaly increases kernel network buffers.
* network-latency: Profile for low latency network tuning. It is based on the latency-performance profile. It additionaly disables transparent hugepages, NUMA balancing and tunes several other network related sysctl parameters.
I'd set network-throughput as the default on a new `set system option performance <throughput | latency>` CLI node which is present in the default configuration.
